Towards a Spacefaring Civilization
Three questions are addressed: (1) Is the U.S. a spacefaring nation? (2) Are we a spacefaring civilization? What are the benefits of being one? If we are not, how do we become one? (3)...

An Analysis of Human Performance in Simulated Partial-Gravity Environments
Three unique partial gravity test environments; parabolic flight, water immersion and a mechanical-relief device provide the environment to evaluate human locomotion, reach sweeps, and...

Internal Pressure in a Lunar Inflatable Structure
Design and construction of a structure on the Moon requires addressing a host of issues not encountered on Earth. A critical design factor is the internal atmospheric pressure necessary...

Integrated Assessment of Environmental Risk and Human Response
Meaningful risk assessment for environmental problems requires an integrated consideration of physical science and human behavioral issues. This is particularly true when dissaggregate...

The Monitoring of Water Conservation Behavior and Attitudes in Southern California
Seldom are the effects of public information programs monitored and analyzed in a sound, systematic manner. Information on the impact of investments in public information programs is essential:...

High Level Radioactive Waste Management 1992
The proceedings of the third International Conference on High Level Radioactive Waste Mnagement, held on April 12-16, 1992, Las Vegas, Nevada, provides information on the technical and...

Full Scale Tests on Concentrically Loaded Fiber-Reinforced Pultruded Columns
This paper briefly reports on the experimental investigation in connection with the short term behavior of pultruded structural members under concentric loading. In particular, results...

Experimental Investigation of Self-Tapping Fasteners for Attachment of Corrugated Cladding Panels to Pultruded Fiber-Reinforced Plastics Beams in Industrial Building Construction
This paper describes an experimental investigation of self-tapping fasteners for the attachment of corrugated fiber-reinforced plastics (FRP) cladding panels to pultruded FRP beams. Although...

Dynamic Design of Deepwater Bottom-Founded Towers
This paper traces the development of dynamic design techniques for deepwater bottom-founded towers by the following: the classification of bottom-founded towers as either `stiff' or `compliant';...

Measured to the Max
Engineers looking to model the behavior of a structure under seismic conditions often ignore the best source of data available: the building itself. Full-scale measurements of vibrations...

Instrumenting the `Y'
Segmental bridges are still relatively new to the U.S. and questions persist about their design and behavior. To expand the knowledge base, a number of laboratory and field studies have...

Stability of Cable-Stayed Brides
This chapter deals only with stability under static loadings. For aerodynamic stabilities and stability of structure under seismic loading, see the appropriate chapters. Both the towers...

The Human Factor in Failures
Human shortcomings cause three-quarters of project failures. A study of 500 case histories led to this assumption. One such failure at the Walter Bouldin dam in Alabama, is described in...

Jailhouse Design
According to statistics from national corrections groups, the inmate population in the U.S. has reached 1 million and could double by 1995. With the constant need for more beds, engineers...

Approximate Methods of Structural Analysis: Principles and Pitfalls
In this modern age when the trend in structural engineering and structural engineering education is to make more and more use of computers and standard structural analysis programs, there...

Structural Approximations in Multi-Story Buildings
Simplified computer analyses and various approximate hand calculation methods are extremely valuable in structural engineering for multi-story buildings both during the preliminary design...

Analysis and Design of Structures with Outrigger Arms
Although sophisticated computer methods are available for analyzing an entire building structure, there is a need for simplified methods (a) for checking the accuracy of the computer analyses,...

High-Level Waste Disposal Regulations: Time for a Change?
Major developments since EPA's high-level radioactive waste disposal regulations were promulgated challenge the validity of some of the assumptions underlying these regulations....

Human Intrusion Scenarios in Nuclear Waste Repository Evaluations
When promulgated, the Environmental Protection Agency (EPA) High Level and Transuranic Waste Standard (40 CFR 191) is expected to require consideration of human intrusion into a nuclear...

The Adoption of Mechanized Excavation Techniques for the Superconducting Super Collider
The Superconducting Super Collider (SSC) is the latest and largest in a line of high-energy physics accelerator projects. The five increasingly energetic accelerators which make up the...
